possible fault location in the future. A cable number and Ergon Energy name shall be provided on the cable. Long Span ADSS cable shall be marked with the words LONG SPAN. The markings are to be legible and indelible and shall not reduce the effectiveness

of the cable in resisting insect and termite attack.

5.3.4 Cable Design The cable is to be of non-metallic construction.




The cable will incorporate a strength member of glass reinforced plastic or equivalent.

The optical fibres shall not be constrained firmly against other fibres, strength members, moisture barrier compound or any other cable components in order that the fibre strain is de-coupled from the strain in other components when the cable is under tension.
